Natural Killer Cell Testing

Immune cells in the uterus are important in the early detection and elimination of foreign cells, such as infections or cancer. These immune cells are normally present in every person as part of their immune system.

Women who have fertility problems, specifically miscarriage or unsuccessful IVF are more likely to have higher levels of activity of these 'Natural Killer cells' [NK cells] than other women. High natural killer cell activity is a form of immunological infertility.

What this means for treatment is still not clear, but a number of different treatments are being trialled. NK Cells is an area of research being undertaken at IVFAustralia for patients who have experienced repeated miscarriage or repeated IVF failure.
